Some Advantages of Solvent-Free, Thick-Film Epoxy Coatings^★

Principal advantages of thick-film, sol-vent-free epoxy coatings are described. The author suggests, because they are not truly volatile-free, that a better term would be “pre-shrunk.” Differences are pointed out between the sol vent-containing and solvent-free epoxies in application, pot life, film thickness and recoat time. Advantages of the thick-film versus solvent-types are to be found in lower application costs per mil, and greater chemical and corrosion resistance. Comparisons of recent tests in salt fog, are given. Some ways in improved are explained Also claimed are longer film life and lack of shrink age during curing. Efforts under way to improve performance are described generally. 5.4.5
